I think that one very good reason for adding sidewalks is simply to allow
better routing for foot traffic.  A great many sidewalks run parallel to
roads without any complicating obstacles or barriers; for those, not only
is this proposal completely sufficient, but it is gives mappers a very
simple way to map them.

I would not support this proposal to the *exclusion* of mapping separate
ways.  Rather, I would support this proposal as the simplest way to add
sidewalk data with the understanding that if a mapper wishes to add
further detail to the sidewalks that they do it via the separate-ways
method.  But I think that a simple tagging approach that covers a great
number of common cases is worth using.
